35*37
First of all multiply the last digits of both the numbers, i.e 5*7=35 and keep 3 as a carry(base=5)
Then multiply the last digit and the first digit of both the numbers, i.e 5*3=15
Then multiply the first digit and the last digit of both the numbers, i.e 3*7=21
Now add both the multiplication, i.e 15+21=36
Remember to add the carry 3, i.e 36+3=39 and keep 3 as carry(base 9)
Now multiply the first digit of both the numbers, i.e 3*3=9 and add the carry 3, i.e 9+3=12(base12)
At last arrange the bases
The first base 5 then the second base 9 and then the last base 12
On arranging from backwards we get 1295
Thus 35*37=1295.

Sir, please let me know whether this method of multiplication is easy or not and also that whether any blunder may be created in this method or not.
Regards.

104*105 =?
==========
Here base =100
Our first No. is 104. Subtract from base i.e. 100 from this No. i.e. 104-100=4 (i)
Our 2nd No. is 105. Subtract from base i.e. 100 from this No. i.e. 105-100=5 (ii)
In first No. i.e. 104 add the balance of second No. i.e. 5
104+5= 109
Multiply (i) and (ii) 4×5=20
Write both result together
Ans. 109 20 i.e. 10920
{Note:-
(x)The multiplication of above balance i.e. (i) and (ii) will be in two digit.
In case of multiplication of three digit like 109×106
In this case it is 20 no problem. But if in any case suppose produce of
multiplication is 6 then write it as 06 (102×103).
(y) Suppose in a case product of multiplication become in three digit then first
digit from left side will be treated as carry to add in next No.
(e.g. 115×110)
============
Second example
Multiply 112×113
============
Our first No. is 112. Subtract from 100 from this No. i.e. 112-100=12 (a)
Our 2nd No. is 113. Subtract from 100 from this No. i.e. 113-100=13 (b)
In first No. i.e. 112 add the balance of second No. i.e. 13
112+13= 125
Multiply (a) and (b) 12×13=156
for 156 we can say product of multiplication is 56 with carry 1 (explained in (x)).
Write both result together
Ans 125 156 (In 156 one is carry which will be add in next No.
= 126 56 (i.e. 125+1=126)
=12656
I want to know that my explanation method is easy or not. If anyone feel problem to understand it then plz. call me on 90 4142 43 22 I will again explain on phone and try to improve the method to explanation method.
Good Night

(28+5)*2 | 8×5
(For base 20 multiply 2. For base 30, multiply by 3 and so on )
=66 | 40
(Since the base is single digit, r.h.s part will have only 1 digit, hence 4 will be carried over to l.h.s and added to 66)
=66+4 | 0
=700

but, u can solve it another method
25 * 28
step 1- u hav to, add the unit place digit.. to the others no…25+8=33
put a zero & multiply it by 2, as it is the ten’s place,
330*2=660
step 2- multiply the unit digit’s of both the no.. 8*5= 40

One more thing is to clear is that after addition in next step is to multiply it with the base
In 25*25 , base is 20
25+8=33
so 33*20=660
To make it easy another way :- place 0 on RHS i.e. 33=330 multiply
it with 2 , 330*2= 660
